  Well, you may just find out when something else stops working - it's not
unknown for people to ship custom toolchains built on Cygwin that install the
DLL into the SYSTEM directory.  (In which case, put the DLL you found there
into the binaries dir alongside the tools involved.)

  Although having them later in the path than the system versions in /usr/bin
should in theory make that safe, mixing DW2 and SJLJ is asking for trouble to
crop up somewhere down the line.
